Preparing for Use
4.1 Unpacking the Device
Remove the device from its packaging and carefully check it for any damage. Should
there be any damage, inform the carrier immediately and keep the packaging to
support any subsequent claims. The original packaging is also useful for transporting
or shipping the device later on.
4.2 Setting up the Device
Before putting the R&S MDS-21 into operation, make sure the following requirements
have been met.
● A non-metallic clamp slide with guiding track is used for the absorbing clamp.
● The absorbing clamp can be easily moved along the test cable.
● The operating current along the test cable does not exceed the permitted limits.
● The maximum permissible RF input power at the device's measuring receiver
output is not exceeded.
When not in use and during transport, the two eccentric catches should not be locked
(see
middle) so that the spring-loaded ferrite holders are released.
4.3 Connecting the Measuring Receiver
Use the supplied 50
coaxial cable with 6 dB attenuator and N angle adapter to
connect the measuring receiver to the test receiver output (N 50
, female).
4.4 6 dB Attenuator
The attenuator is permanently connected to the measurement cable and attenuates
the disturbance power emitted from the EUT by 6 dB.
The attenuator reduces the mismatch between the output of the absorbing clamp and
the measuring receiver.
